The Huygens probe, supplied by the European Space Agency (ESA) and named after the 17th century Dutch astronomer who first discovered Titan, Christiaan Huygens, scrutinized the clouds, atmosphere, and surface of Saturn's moon Titan in its descent on January 15, 2005. It was designed to enter and brake in Titan's atmosphere and parachute a fully instrumented robotic laboratory down to the surface. The probe system consisted of the probe itself which descended to Titan, and the probe support equipment (PSE) which remained attached to the orbiting spacecraft. The PSE includes electronics that track the probe, recover the data gathered during its descent, and process and deliver the data to the orbiter that transmits it to Earth. The core control computer CPU was a redundant MIL-STD-1750A control system. The data were transmitted by a radio link between Huygens and Cassini provided by Probe Data Relay Subsystem (PDRS). As the probe's mission could not be telecommanded from Earth because of the great distance, it was automatically managed by the Command Data Management Subsystem (CDMS). The PDRS and CDMS were provided by the Italian Space Agency (ASI). Huygens communications would have been entirely lost if not for testing in flight that discovered a Doppler-related problem, requiring a change in orbital trajectories to compensate.

Titan Touchdown

On Jan. 14, 2005, ESA's Huygens probe made its descent to the surface of Saturn's hazy moon, Titan. Carried to Saturn by NASA's Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the probe during its two-and-a-half hour fall under its parachutes.
Huygens was a signature achievement of the international Cassini-Huygens mission, which will conclude on Sept. 15, 2017, when Cassini plunges into Saturn's atmosphere.

Huygens descent to Titan in 360°

Huygens was an atmospheric entry probe that landed successfully on Saturn's moon Titan in 2005, it was part of the Cassini–Huygens mission and became the first spacecraft ever to land on Titan and the furthest landing from Earth a spacecraft has ever made.
Huygens was designed to enter and brake in Titan's atmosphere and parachute a fully instrumented robotic laboratory to the surface. When the mission was planned, it was not yet certain whether the landing site would be a mountain range, a flat plain, an ocean, or something else, and it was hoped that analysis of data from Cassini would help to answer these questions. Assuming the landing site could be non-solid, Huygens was designed to survive the impact, splash down on a liquid surface on Titan, and send back data for several minutes on the conditions.
The spacecraft had no more than three hours of battery life, most of which was planned to be used during the descent. Engineers expected to get at most only 30 minutes of data from the surface.

The Huygens experience

A new rendering of Huygens descent and touchdown created using real data recorded by the probe's instruments as it descended to the surface of Titan, Saturn's largest moon, on 14 January 2005.
The animation takes into account Titan's atmospheric conditions, including the Sun and wind direction, the behaviour of the parachute (with some artistic interpretation only on the movement of the ropes after touchdown), and the dynamics of the landing itself. Even the stones immediately facing Huygens were rendered to match the photograph of the landing site returned from the probe, which is revealed at the end of the animation.
Split into four sequences, the animation first shows a wide-angle view of the descent and landing followed by two close-ups of the touchdown from different angles, and finally a simulated view from Huygens itself - the true Huygens experience.
This animation was released 14 January 2013 on the eighth anniversary of Huygen's touchdown on Titan.

Huygens's descent to Titan's surface

On 15 October 1997, NASA's Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA's Huygens probe, destined for Saturn's largest moon, Titan. The final chapter of the interplanetary trek for Huygens began on 25 December 2004 when it deployed from the orbiter for a 22-day solo cruise toward the haze-shrouded moon. Plunging into Titan’s atmosphere, on 14 January 2005, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface.
This narrated movie, created with data collected by the Huygens Descent Imager/Spectral Radiometer (DISR), depicts the view from Huygens during the last few hours of this historic journey.
This new version of the movie uses updated DISR data and was released on 14 January 2015 on the occasion of the 10th anniversary of Huygen's landing on Titan.

KSP - Cassini–Huygens - Pure Stock Replicas [Old]

Cassini update, must watch: https://youtu.be/chB1v2WsDWk
The craft has just about enough Delta V to burn into a low Jool orbit however using gravity assists like the ones shown in the video will reduce the fuel consumption drastically giving you an almost unlimited ability to explore the system.
The replica is very true to real life, the main differences being that instead of Cassini's gold thermal blankets I've bathed the probe in golden coloured light. Also the Huygens probe was designed to float in case it landed in liquid but this stock version will sink.

Huygens (spacecraft) - Video Learning - WizScience.com

""Huygens"" was an atmospheric entry probe that landed successfully on Saturn's moon Titan in 2005. Built and operated by the European Space Agency , it was part of the "Cassini–Huygens" mission and became the first spacecraft ever to land on Titan. The probe was named after the Dutch 17th-century astronomer Christiaan Huygens, who discovered Titan in 1655.
The combined "Cassini–Huygens" spacecraft was launched from Earth on October 15, 1997. "Huygens" separated from the "Cassini" orbiter on December 25, 2004, and landed on Titan on January 14, 2005 near the Xanadu region. This was the first landing ever accomplished in the outer Solar System. It touched down on land, although the possibility that it would touch down in an ocean was also taken into account in its design. The probe was designed to gather data for a few hours in the atmosphere, and possibly a short time at the surface. It continued to send data for about 90 minutes after touchdown. It remains the most distant landing of any human-made craft.
"Huygens" was designed to enter and brake in Titan's atmosphere and parachute a fully instrumented robotic laboratory to the surface. When the mission was planned, it was not yet certain whether the landing site would be a mountain range, a flat plain, an ocean, or something else, and it was hoped that analysis of data from "Cassini" would help to answer these questions.
Based on pictures taken by "Cassini" at 1,200 km above Titan, the landing site appeared to be a shoreline. Assuming the landing site could be non-solid, "Huygens" was designed to survive the impact, splash down on a liquid surface on Titan, and send back data for several minutes on the conditions. If that occurred it was expected to be the first time a human-made probe would land in an extraterrestrial ocean. The spacecraft had no more than three hours of battery life, most of which was planned to be used during the descent. Engineers expected to get at most only 30 minutes of data from the surface.

Cassini–Huygens timeline - Video Learning - WizScience.com

This page lists a chronology of events which have occurred or are expected to occur during the Cassini–Huygens mission to Saturn and Titan.
"October 15" 01:43 Pacific Daylight Time – Cassini launched at 08:43 UTC inside Titan IVB/Centaur rocket.
The initial gravitational-assist trajectory of "Cassini–Huygens" is the process whereby an insignificant mass approaches a significant mass "from behind" and "steals" some of its orbital momentum. The significant mass, usually a planet, loses a very small proportion of its orbital momentum to the insignificant mass, the space probe in this case. However, due to the space probe's small mass, this momentum transfer gives it a relatively large velocity increase in proportion to its initial velocity, speeding up its travel through outer space.
The "Cassini–Huygens" space probe performed two gravitational assist fly-bys at Venus, one more fly-by at the Earth, and a final fly-by at Jupiter.
"April 26" 06:52 PDT – Gravity-assisted flyby of Venus at 284 km, receiving a boost in speed of about 7 kilometers per second.
"December 3" 22:06 PDT – Cassini fired its main rocket engine for 90 minutes, setting the spacecraft on course for its second Venus flyby in 1999. The engine burn slowed the spacecraft by close to 450 meters per second relative to the Sun. Cassini's speed went from 67,860 kilometers per hour at the start of the maneuver to 66,240 kilometers per hour at the end of the engine firing.
"June 24" 13:30 PDT – Gravity-assisted flyby of Venus at 623 km.

Cassini–Huygens - Video Learning - WizScience.com

""Cassini–Huygens"" is an unmanned spacecraft sent to the planet Saturn. It is a flagship-class NASA–ESA–ASI robotic spacecraft. "Cassini" is the fourth space probe to visit Saturn and the first to enter orbit, and its mission is ongoing as of 2015. It has studied the planet and its many natural satellites since arriving there in 2004.
Developed starting in the 1980s, the design includes a Saturn orbiter, and a lander for the moon Titan. The lander, called "Huygens", landed on Titan in 2005. The two-part spacecraft is named after astronomers Giovanni Cassini and Christiaan Huygens.
The spacecraft launched on October 15, 1997 aboard a Titan IVB/Centaur and entered orbit around Saturn on July 1, 2004, after an interplanetary voyage that included flybys of Earth, Venus, and Jupiter. On December 25, 2004, "Huygens" separated from the orbiter and reached Saturn's moon Titan on January 14, 2005. It entered Titan's atmosphere and descended to the surface. It successfully returned data to Earth, using the orbiter as a relay. This was the first landing ever accomplished in the outer Solar System.
Sixteen European countries and the United States make up the team responsible for designing, building, flying and collecting data from the "Cassini" orbiter and "Huygens" probe. The mission is managed by NASA’s Jet Propulsion Laboratory in the United States, where the orbiter was assembled. Huygens was developed by the European Space Research and Technology Centre. The Centre's prime contractor, Aérospatiale of France , assembled the probe with equipment and instruments supplied by many European countries . The Italian Space Agency provided the "Cassini" orbiter's high-gain radio antenna, with the incorporation of a low-gain antenna , a compact and lightweight radar, which also uses the high-gain antenna and serves as a synthetic aperture radar, a radar altimeter, a radiometer, the radio science subsystem , the visible channel portion VIMS-V of VIMS spectrometer. The VIMS infared counterpart was provided by NASA, as well as Main Electronic Assembly, which includes electronic subassemblies provided by CNES of France.

STORYLINE:
The European-built Huygens probe has separated on schedule from the Cassini spacecraft in orbit around Saturn, starting a three-week free-fall toward Saturn''s moon Titan.
The Huygens probe is equipped with instruments to sample the chemistry of the planet-size moon''s thick atmosphere, and may reveal whether it actually has lakes or seas of liquid hydrocarbons that have been theorised by scientists.
A signal confirming release of the probe was received at NASA''s Jet Propulsion Laboratory in Pasadena California at 0324 GMT Saturday.
The separation had taken place earlier, but it took more than an hour for radio signals to cross the hundreds of millions of kilometres between Saturn and Earth.
Smiles broke out in the JPL control room where many members of the mission staff wore red and white Santa hats.
The aim had to be good because Huygens has no manoeuvring system to adjust its own course, and it was designed to remain dormant until just before hitting Titan''s atmosphere on 14 January.
A detailed analysis of data from the release was under way, but there were no indications of any problems, said Earl Maize, the Cassini deputy program manager at JPL.
Cassini was equipped with springs to gently push the 320-kilogram Huygens probe away at a rate of 30 centimetres per second and impart a stabilising spin of seven revolutions per minute.
Next week Cassini will make a course change to avoid following Huygens into Titan''s atmosphere.
Huygens was designed for only a brief mission.

Approaching Titan a Billion Times Closer

Remember the Titan (Landing): Ten years ago today, Jan. 14, 2005, the Huygens probe touched down on Saturn's largest moon, Titan.
This new, narrated movie was created with data collected by Cassini's imaging cameras and the Huygens Descent Imager/Spectral Radiometer (DISR). The first minute shows a zoom into images of Titan from Cassini's cameras, while the remainder of the movie depicts the view from Huygens during the last few hours of its historic descent and landing.
It was October 15, 1997, when NASA's Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA's Huygens probe, destined for Saturn's largest moon, Titan. The final chapter of the interplanetary trek for Huygens began on 25 December 2004 when it deployed from the orbiter for a 21-day solo cruise toward the haze-shrouded moon. Plunging into Titan's atmosphere, on January 14 2005, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface. Today, the Cassini spacecraft remains in orbit at Saturn. Its mission will end in 2017, 20 years after its journey began. More information and images from the mission at http://saturn.jpl.nasa.gov

This animation was released on the eighth anniversary of Huygen's touchdown on Titan as a Space Science Image of the Week feature.

A new rendering of Huygens descent and touchdown created using real data recorded by the probe's instruments as it descended to the surface of Titan, Saturn's largest moon, on 14 January 2005.
The animation takes into account Titan's atmospheric conditions, including the Sun and wind direction, the behaviour of the parachute (with some artistic interpretation only on the movement of the ropes after touchdown), and the dynamics of the landing itself. Even the stones immediately facing Huygens were rendered to match the photograph of the landing site returned from the probe, which is revealed at the end of the animation.
Split into four sequences, the animation first shows a wide-angle view of the descent and landing followed by two close-ups of the touchdown from different angles, and finally a simulated view from Huygens itself -- the true Huygens experience.

The Sound of Saturn: The Winds of Titan, from the Huygens Probe

The actual sound recording from the Huygens Probe as it descends through the methane atmospheres of Titan, to land on the surface of this moon of Saturn.
This is the sound of the landing on another body in our solar system most distant from the earth.
Professor Carolin Crawford, Gresham Professor of Astronomy, introduces the recording, describing the 2 1/2 hour descent through the methane winds blowing at 6 to 7 km per hour. She then goes on to explain why we haven't yet been able to hear the sound of the atmosphere of Mars, and how we might be able to soon.
This is an extract from a free public lecture by Carolin Crawford, Gresham Professor of Astronomy: 'The Sounds of the Universe'.
The transcript and downloadable versions of the full hour-long lecture are available from the Gresham College website:

Cassini-Huygens in orbit around Saturn

Huygens will be the first probe to land on a world in the outer Solar System - on the surface of Titan, Saturn's largest moon. The Huygens data may offer clues about how life began on Earth. Huygens is currently in space, hitching a ride on NASA's Cassini spacecraft.

Huygens Landing on Titan

I do not know where I got this video from, but if you are into space exploration you will find this interesting. The video details the Huygens probe landing on Titan after being launched by Cassini.

Huygens: Titan Descent Movie (2005.01.14)

This movie was built thanks to the data collected by ESA's Huygens Descent Imager/Spectral Radiometer (DISR) on 14 January 2005, during the 147-minutes plunge through Titan's thick orange-brown atmosphere to a soft sandy riverbed.
In 4 minutes 40 seconds, the movie shows what the probe 'saw' within the few hours of the descent and the eventual landing. At first the Huygens camera just saw haze over the distant surface. The haze started to clear only at about 60 kilometers altitude, making it possible to resolve surface features as large as 100 meters. Only after landing could the probe's camera resolve little grains of sand millions and millions times smaller than Titan. The movie provides a glimpse on such a huge change of scale.

Carl Sagan's Cosmos: Dutch Golden Age (1/3)

"The world is my country, science my religion" - Christiaan Huygens (1629-1695)
Excerpt from Carl Sagan's legendary 'Cosmos' series.
Sagan discusses the period in Dutch history that is known as the "Dutch Golden Age" (roughly spanning the 17th century). During and after the war of independence ('the Eighty Years' War' (1568-1648)) against the Spanish empire, the Dutch Republic experienced its own Enlightenment which left a profound mark on modern civilization. Amongst the countless revolutionary Dutch inventions from this period are the microscope, telescope, the stock exchange, and the first publicly traded multinational corporation (Dutch East India Company). This period also produced some of the world's most famous painters like, e.g., Rembrandt and Vermeer.
Great books on the Dutch Republic are Jonathan Israel's 'The Dutch Republic' and 'Radical Enlightenment'. Simon Schama's 'The Embarrassment of Riches' is also a fantastic read.

ESA Euronews: Saturn probe could tell us more about life on Earth

In January 2005 the Huygens probe landed on Titan, the biggest of Saturn's moons. It was the first earth-born object to land in the outer solar system. Now, new discoveries by the Cassini-Huygens mission could change our assumptions about the presence of life in the Solar System.

New analysis of Cassini data indicates Saturn's moon Titan has more in common with Earth than we thought.

Hi-res narrated video of Huygens probe landing

This movie narrates the 147-minute descent of the European Space Agency's Huygens Descent Imager/Spectral Radiometer probe in just a few minutes. You can see the probe landing from different angles.

Cosmic Vision - See how Huygens landed on Titan

After an epic space journey, the European Huygens probe landed on Saturn's moon Titan, a mysterious satellite that has perplexed astronomers for decades. On 14 January 2005, Huygens made the farthest touchdown of any human-built object sent to land on another world.

Routing Cassini through space to Titan - BBC

To get enough speed to reach Titan, Cassini would have to use other planets as sling-shots to propel her out into the far reaches of our solar system. Scientists explain how this is done in this fascinating BBC clip.

The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space Time Journal Club to reveal another clue. We’re looking at a new paper in Nature Astronomy, “Cosmological constraints from the Hubble diagram of quasars at high redshifts” by Risaliti and Lusso. It hints that the cosmological constant may not be so constant after all. In fact it may be increasing. If this is true, then our prediction for the future of our universe looks VERY different, and may involve the entire universe tearing itself to shreds at the subatomic level in the Big Rip.
On this edition of Space Time Journal Club we look at:

NASA ScienceCasts: A Super Start to 2019

2019 is an excellent year to look to the sky and enjoy the spectacular view of Earth’s nearest neighbor, the Moon.

Do black holes contain dark matter?

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes?
Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough.
This was a really fun speculative question to think about, especially because it ties in with my PhD thesis too. Let me know if you want me to do a video describing my thesis down in the comments.
Both my lapel microphones ran out of battery this week. Thankfully one of them didn't need a battery to use with a smartphone, so the sound was recorded that way. It's not brilliant I know, but it'll do. My research schedule this week stopped me from delaying filming until I could get a battery. The sound suffered so science wouldn't.

Space Weather News | A Filament Sandwiched by Sunspots 03.20.2019

UPDATE: Part of the filament I talk about did erupt after I posted this video! We could have a part-Earth directed solar storm coming by the end of this week! Check my twitter feed for the latest on arrival time!
Original Video Description:
This week we are coming down from a solar storm from some fast solar wind, but that doesn't mean the fun is over! We have two fast-growing sunspots on the Earth-facing Sun and they are sandwiching a filament that is growing more unstable by the day. If this filament erupts within the next day or so, we could have an Earth-directed solar storm! We are keeping a close watch on this to be sure. Also, one of the new sunspots may be showing signs of an influence of solar cycle 25. Just like the previous rogue sunspot we saw a few weeks ago, this new region has a dominant magnetic signature that runs north-south instead of east-west. Its too early to tell what the final polarity of this region will be, but if it continues this way, it will be yet another signal that solar cycle 25 is closer than we think! Learn the details of this filament sandwich, get the scoop on the two new sunspots that may cause its launch, and see what else our Sun has in store for us this week!
